In his previous life, Shen Wei was a top mechanical engineer who built a strong shelter for his family in the apocalypse and awakened his "metal affinity" power. He fought tooth and nail to protect his family, but when the zombies came and supplies were in short supply, his limbs were broken by his mother Zhao Huilan and his stepbrother Lin Yu, and they were thrown out of the shelter as bait to lure away the zombies, just to save a bite of food. When Shen Wei was eaten by zombies, his resentment surged to the sky, and he was accidentally reborn one month before the apocalypse broke out. In this life, he is no longer a Holy Mother. He voluntarily gave up his mansion in the city center and used tens of billions of funds from selling off his assets to transform an abandoned heavy industry machinery factory in the suburbs into the most powerful "mechanical fortress" in the apocalypse. He holds the super AI "Regent" obtained in his previous life, hoards billions of supplies, and wants to establish the only order in the apocalypse.
